AITA for not sharing my food with my roommate’s friend even though my roommate said it was ok?

I(22M) live in an apartment with my roommate (23F) and we’re both sober. Yesterday she had plans with a friend (25M), but he doesn’t drink so he came back to our place to hang out. It was supposed to rain all day but instead it was kinda cloudy but not that bad so I had an idea and said “the weather’s nice out, you guy wanna play some lacrosse?” <br><br>We went to a park nearby our apartment and played some lacrosse for a few hours. When we got back Star our roommate had woken up and made us snacks. It was basically a lot of junk food I’d bought that she used to make some tasty snack mix stuff along with some fruit and cheese, and I said, “Hey, I’m gonna take this out onto my balcony and meet you guys back inside in a bit!” But really I took the snack mix and went down to the community pool and swam for a few hours. When I got back at night my roommate asked me what the snack mix had looked like and I said, “You know, the usual, some Reese’s Pieces, some M&M’s, some Cheerios, the normal stuff.” And she was like “no, you also put some of that red fruit in it and some of that cheese, right?” And I was like, “Yeah, no, I only used the Reese’s Pieces and the M&M’s” and she went “oh, ok.”<br><br>So apparently her friend had been really looking forward to playing lacrosse but when we got back her friend was like “Hey, wanna get some food?” and she was like “yeah, I could go something” so I said, “Well there was this snack mix thing at that spot and I swam in the pool and then I got back here and that’s it.” And she just gives me this look and is like “you didn’t share the snack mix?” And I was like “no, I shared it with Star, just not you two” and she went “yeah, we were looking forward to it.” <br><br>Now I guess her friend is pissed at me because I didn’t share the snack mix even though my roommate said it was okay, so AITA?
